Abstract
A system and method for selective heating and/or sintering of a material including first and second substrates, an array of one or more resistive heating elements arranged on a planar surface of a substrate and material to be heated located on the other substrate.
Claims27
A printhead for selective heating of a material comprising:
- a substrate;
- an array of one or more resistive heating elements arranged on a planar surface of said substrate;
- each heating element in electrical communication with a pair of interconnects;
- and
- said interconnects contact said heating elements and then extend away from said planar surface.
2 more elements
A system for selective heating of a material comprising:
- a first substrate, said first substrate configured to support an array of one or more resistive heating elements arranged on a planar surface of said substrate;
- each heating element in electrical communication with a pair of interconnects;
- a second substrate configured to support a material to be heated;
- said first and second substrates positioned to form a gap between said resistive heating elements and said material;
- and
- a drive to selectively position said resistive heating elements and said material with respect to one another.
3 more elements
A method for the selective heating of a material comprising the steps of:
- providing a first substrate, said first substrate configured to support an array of one or more resistive heating elements arranged on a planar surface of said substrate;
- each heating element in electrical communication with a pair of interconnects;
- providing a second substrate configured to support a material to be heated;
- positioning said first and second substrates to form a gap between said resistive heating elements and said material;
- and
- selectively positioning and activating said resistive heating elements and said material with respect to one another to form a pattern of heated material.
